[CMake] MinGW - Qt Linking problems

[Vitor Vasconcelos Araujo Silva]

	Hello all,

	I'm experiencing weired problems when trying to link my application 
with MinGW.

	After generate my Makefile I have the Qt libraries added but no -l 
options for Qt libraries. My "linking" line is this:

g++      "CMakeFiles/oigui.dir/oigui.cpp.obj"  -o oigui.exe 
-Wl,--out-implib,liboigui.dll.a 
-Wl,--major-image-version,0,--minor-image-version,0  -LZ:\studies 
-LC:\Qt\4.3.4-static\lib -lqgarwin C:\Qt\4.3.4-static\lib\libQtCore.a 
C:\Qt\4.3.4-static\lib\libQtGui.a C:\Qt\4.3.4-static\lib\libQtXml.a
-lmingw32 -lqtmain -lgdi32 -lcomdlg32 -loleaut32 -limm32 -lwinmm 
-lwinspool -lmsimg32 -lkernel32 -luser32 -lshell32 -luuid -lole32 
-ladvapi32 -lws2_32

	With this, I have missing symbols for all calls to Qt functions. Of 
course, if I add:

–lQtCore –lQtGui –lQtXml

  	To my linking line, everything links ok.
	This problem does not occurs on Linux with gcc, but only with MinGW. My 
point is, am I missing some point in my project's configuration?

	I added my CMakeLists.txt to clarify.
	
	Another important remark is that my Qt version is compiled as static. 
So, I have no dll's available, only .a files.

	Thanks in advance,
