68866b1a7b Fix QMAKE_EXTRA_COMPILER names in VS projects
Use the whole value of 'name', not just the first element, and also
replace variables like ${QMAKE_FILE_IN}.

This fixes the file_copies feature (COPIES) for Visual Studio
projects, because for every entry in COPIES an extra compiler is
created with a name 'COPY ${QMAKE_FILE_IN}'. Before this patch the
name and the generated file filter would be just 'COPY'. However,
duplicate filters are being skipped by the VS project generator. All
but the first COPIES entry was ignored.

target information available in Visual Studio. $(TargetFileName) is
documented as "The file name of the primary output file for the build

$(TargetName) together with ".exe".

2dcfaf7bee qmake/vcxproj generator: Fix bug in extra compiler initialization
QMake ignored every extra compiler that sets variable_out and whose

What the code wants to achieve is to ignore extra compilers that put
their output into variables that are handled "somewhere else already",
e.g. are in the otherFilters list. Evidence for that is to be found in
the addOnInput == true if branch.

29d5a287ab Make the Makefile a dependency of default targets for nmake
If the user changes the .pro file, the Makefile is supposed to be
re-generated by calling qmake again. NMake however lacks a "Makefile
remake feature" like GNU make has.

The generated Makefiles for nmake however have already a proper
Makefile target that can be used to re-generate the Makefile. What was
missing is the dependency from an entry-target in the meta-Makefile.

Now changes in the .pro file trigger a re-generation of
Makefile.Debug/Makefile.Release when calling nmake without target
arguments or with "debug" or "release".

6a221f3d05 Fix qmake's detection for conflicting source files for nmake
Consider the following source tree:
  foo/narf.cpp
  bar/narf.c
  bar/gnampf.cpp

The .pro file has
  SOURCES += foo/narf.cpp bar/gnampf.cpp
The file bar/narf.c is not supposed to be built for whatever reason.

QMake's nmake Makefile generator generates inference rules of the form

  {.\foo}.cpp{debug\}.obj::
  ...

for every source subdirectory and every source file extension.
Thus, we have

  {.\foo}.cpp{debug\}.obj::
  {.\bar}.cpp{debug\}.obj::
  {.\bar}.c{debug\}.obj::

Depending on the exact execution order of the inference rules (which
depends on the names of the files) the latter rule might get picked,
and we're erronously compiling bar/narf.c even though it's not
referenced in the .pro file.

Conclusion: QMake's detection of conflicting source files must
consider the base names of source files, and not the exact file names.

We now treat -o foo/bar/baz as a request to generate the output in the

a directory, in the foo/bar/baz directory with the default output name.

We take care to handle generator specific directory structures, so
that the project directory does not get merged into OUT_PWD. This is
done in runQmake(), before parsing the project file, so that OUT_PWD
will be correct during project parsing. The individual generators are
then passed the filename relative to the final output directory.

Each generator now also makes sure to add the right project suffix
to the output file, so -o foo will result in foo.pro or foo.vcproj,
instead of just foo.

6b4f2f7556 qmake: get rid of (some) makefile expansions in dependency paths
the variables are quoted correctly for commands, which is incompatible
with quoting for dependencies under mingw. so insert the paths as
literals, where we can control quoting.

this fixes building in directories with spaces, which i broke in
7c34e0a7b by using different quoting styles for deps and commands in the
first place.

this breaks the hypothetical use case where somebody wants to override
TARGET or DESTDIR (or DESTDIR_TARGET under windows) on the *make*
command line. not sure why anyone would do that - just do it at the
*qmake* level.

we did not get rid of OBJECTS, because that would cause significant
duplication in the makefile (not that it would matter too much, given
the dependency lists ...). this isn't a problem, because these are
short relative paths which are not expected to contain "funny"
characters.

an alternative would have been to change the variables' quoting and
eliminate them from the commands instead, but that would be
backwards-incompatible, because commands are "user-servicable".
for the same reason, we cannot get rid of the variables entirely.

under windows, libraries can have a numeric suffix derived from VERSION,

have. therefore, we had to make the back-mapping from the library to the

we actually got the right file by comparing the target specified inside
the .prl file with what we started from.

this fixes linking of transitive deps of static deps.

the alternative of changing the .prl naming pattern to avoid the
back-mapping was discarded, as a) it would be backwards incompatible and
b) it would break project-internal -lfoo references to versioned libs.

these characters can appear in file names, but are meta characters in
dependency context. they have different semantics in make commands, so
this required some reshuffling in the windows generator (which just
treated dependencies and commands the same way).

we don't actually escape colons for nmake, because it has magic
treatment of drive letters anyway (and colons cannot appear elsewhere).
also, if a target's filename gets quoted, batch rules will blow up.
therefore, "funny" file names are really only supported as inputs -
which is just enough to make resource embedding work.

0f9f716f36 doc: Remove inappropriate qdoc comment markers
Removed the '!' from two comments because the functions being
documented are static functions declared and defined in the
.cpp file. They are not public.

af1a179cc8 qmake: Introduce precompile_header_c for MSVC
MSVC requires that the C PCH file is compiled (as an object) and linked if
any C file is found, and the same for C++.

Most qmake projects are C++.

If a C++ project has a precompiled header, it is typically of C++ type, and
cannot be compiled as C (for example, it contains or includes classes).

Since there is no easy way to conditionally build the C PCH file only if C
files are found in the project (as done for g++), we need a setting that is
disabled by default.

This amends 30331afda1.

[ChangeLog][Tools][qmake] Introduced precompile_header_c CONFIG option for
MSVC to enable precompiled header for C sources.
