liblzma/CMakeLists.txt
Lasse Collin 474320e990 Build: Fix bugs in the CMake files.
Seems that the phrase "add more quotes" from sh/bash scripting
applies to CMake as well. E.g. passing an unquoted list ${FOO}
to a function that expects one argument results in only the
first element of the list being passed as an argument and
the rest get ignored. Adding quotes helps ("${FOO}").

list(INSERT ...) is weird. Inserting an empty string to an empty
variable results in empty list, but inserting it to a non-empty
variable does insert an empty element to the list.

Since INSERT requires at least one element,
"${CMAKE_THREAD_LIBS_INIT}" needs to be quoted in CMakeLists.txt.
It might result in an empty element in the list. It seems to not
matter as empty elements consistently get ignored in that variable.
In fact, calling cmake_check_push_state() and cmake_check_pop_state()
will strip the empty elements from CMAKE_REQUIRED_LIBRARIES!

In addition to quoting fixes, this fixes checks for the cache
variables in tuklib_cpucores.cmake and tuklib_physmem.cmake.

Thanks to Martin Matuška for testing and reporting the problems.
These fixes aren't tested yet but hopefully they soon will be.

#
# Very limited CMake support for building some parts of XZ Utils
#
# For now, this is indented to be useful to build static or shared liblzma
# on Windows with MSVC (to avoid the need to maintain Visual Studio project
# files). Building liblzma on a few other platforms should work too but it
# is somewhat experimental and not as portable as using ./configure.
#
# On some platforms this builds also xz and xzdec, but these are
# highly experimental and meant for testing only:
# - No large file support on those 32-bit platforms that need it
# - No replacement getopt_long(), libc must have it
# - No sandboxing support
# - No translations
# - No xz symlinks are installed
#
# Other missing things:
# - No xzgrep or other scripts or their symlinks
# - No tests (no test failures either!)
#
# NOTE: Even if the code compiles without warnings, the end result may be
# different than via ./configure. Specifically, the list of #defines
# may be different (if so, probably this CMakeLists.txt got them wrong).
#
# This file provides the following installation components (if you only
# need liblzma, install only its components!):
# - liblzma_Runtime
# - liblzma_Development
# - xz (on some platforms only)
# - xzdec (on some platforms only)
#
# To find the target liblzma::liblzma from other packages, use the CONFIG
# option with find_package() to avoid a conflict with the FindLibLZMA module
# with case-insensitive file systems. For example, to require liblzma 5.2.5
# or a newer compatible version:
#
# find_package(liblzma 5.2.5 REQUIRED CONFIG)
# target_link_libraries(my_application liblzma::liblzma)
