An MSVC debug-and-release build of Qt with the MySQL plugin requires
separate builds of the MySQL client library: a debug and a release
build. There was no way to specify the debug version of the library.
Now, it's possible to configure Qt like this:
cmake ... \
-DMySQL_ROOT=D:\mysql-connector-c-6.1.11-winx64 \
-DMySQL_LIBRARY_DIR=D:\mysql-connector-c-6.1.11-winx64\lib\vs14
This will automatically detect the include dir and the debug and release
library files. We expect that the debug build of the MySQL client
library resides in a "debug" subdirectory below MySQL_LIBRARY_DIR.
If the automatic detection doesn't work to due a different layout on the
build machine, one can set the variable MySQL_LIBRARY_DEBUG to specify
the debug variant of the MySQL client library.
[ChangeLog][CMake] If pkg-config is not used, a debug build of the MySQL
client library can be specified with
-DMySQL_LIBRARY_DEBUG=<path-to-library>. The debug and release variants
of the library are automatically detected. Setting MySQL_ROOT and
MySQL_LIBRARY_DIR is sufficient in most cases.
