Summary0015928: FindwxWidgets Fails
DescriptionWhen I try to use FindwxWidgets in CMake 3.4.1, I keep getting the following error:
CMake Error at /usr/share/cmake/Modules/FindwxWidgets.cmake:870 (message):
   wxWidgets wx/version.h file not found in
   /home/User/Code/wxWidgets/win_build32/lib/wx/include/i686-w64-mingw32-msw-unicode-static-3.0;/home/User/Code/wxWidgets/include.

Even though the file exists and I've even made a symlink in the other location to make sure. In either case, I get that error. However, if I downgrade to CMake 3.3.2, everything works as it should.

The full path to wx/version.h is /home/User/Code/wxWidgets/include/wx/version.h.

In CMakeCache.txt, the _filename variable is set as follows: _filename:FILEPATH=_filename-NOTFOUND

It's set to this value in both the CMakeCache.txt for 3.3.2 and 3.4.1. In testing, I even deleted the working directory and started from a clean slate and the issue still occurred with 3.4.1.

This is under Fedora 23 and cross-compiling using MinGW. The wxWidgets library is self-compiled.

CMAKE_FIND_ROOT_PATH is set to usr/x86_64-w64-mingw32/sys-root/mingw or /usr/i686-w64-mingw32/sys-root/mingw depending on which architecture I'm building for. I use a mixture of libraries from the repos and self-built, though.

CMAKE_FIND_ROOT_PATH_MODE_INCLUDE is set to ONLY.

Manually passing -D_filename=/home/User/Code/wxWidgets/include/wx/version.h when I run the CMake configuration fixes the issue.

Are you using the mingw helper?

i.e.:
mingw32-cmake /path/to/CmakeFiles.txt

Yep. I use mingw64-cmake for 64-bit and mingw32-cmake for 32-bit.
