[AD] [A4.4.1.1] Windows profile build fails

[Edgar <edgarreynaldo@xxxxxxxxxx>]

Using

/cmake -DWANT_ALLEGROGL=on -DWANT_LOADPNG=on -DWANT_LOGG=on 
-DWANT_JPGALLEG=on -DCMAKE_BUILD_TYPE=Profile -DSHARED=on -G "MinGW 
Makefiles" ../

and running make gives these errors :

/Linking C shared library lib\alleg44-profile.dll

From running 'make -B -n' and examining the output, here is the command 
that builds the Allegro profile library :

/"C:\Tools\CMake\CMake 2.8\bin\cmake.exe" -E cmake_link_script 
CMakeFiles\allegro.dir\link.txt --verbose=/

The contents of allegro/build/CMakeFiles/allegro.dir/link.txt are :

/C:\mingw\bin\gcc.exe    -shared -o lib\alleg44-profile.dll 
-Wl,--out-implib,lib\liballeg44-profile.dll.a 
-Wl,--major-image-version,4,--minor-image-version,4 
-Wl,@CMakeFiles\allegro.dir\objects1.rsp -lkernel32 -luser32 -lgdi32

-loleaut32 -luuid -lcomdlg32 -ladvapi32/

If I guess correctly, the undefined references to 'mcount' are because 
the '-pg' flag was missing during the profiling library build.

I looked at allegro/CMakeLists.txt and on lines 314-321 it sets 
CMAKE_EXE_LINKER_FLAGS_PROFILE to "-pg" if COMPILER_GCC is set :

/if(COMPILER_GCC)
   set(CMAKE_C_FLAGS_PROFILE "-pg"
       CACHE STRING "profiling flags")
   set(CMAKE_CXX_FLAGS_PROFILE "${CMAKE_C_FLAGS_PROFILE}"
       CACHE STRING "profiling flags")
   set(CMAKE_EXE_LINKER_FLAGS_PROFILE "-pg"
       CACHE STRING "profiling flags")
endif(COMPILER_GCC)/

So, shouldn't it be linking with the '-pg' flag then? Or is there some 
COMPILER_MINGW variable that needs to be checked.

How do you set a libraries linking flags with cmake?

Any ideas how to fix this? The profiling build works fine on openSUSE 11.3.

(Using MinGW 3.4.5 on Vista with CMake 2.8)

Thanks, Edgar.
