[CMake] FindModules vs EXEC_PROGRAM

[Werner Smekal]

Hi Stephen,

the module should work without problems for Linux as long as (the 
correct) wx-config is in the path environment variable. The module does 
practically the same as you do with EXEC_PROGRAM. So if you 
CMakeLists.txt works, the wxWidgets cmake module should also work.

Find the module FindwxWidgets.cmake and uncomment line 100

  # MESSAGE(STATUS 
"${CMAKE_CURRENT_LIST_FILE}(${CMAKE_CURRENT_LIST_LINE}): ${_MSG}")

to get some debug messages. Maybe this gives you a hint what is wrong.

Regards,
Werner
