[CMake] CMake does not find an header file, and ignores the classes found in several other header files.

[Toronto Andrew]

Hello, thank you for looking at my CMake issues! I really appreciate it :)

I fixed the major issue you mentioned (Moving INCLUDE_DIRECTORIES above
ADD_EXECUTABLE), however this did not seem to fix anything. I still got the
errors I was receiving prior to that change, and I used absolute paths when
linking to the include directory within my source. 

I fixed this *qextserialport\src\moc_qextserialport.cpp(10): fatal error
C1083: Cannot open include file: '../../../src/qextserialport.h': No such
file or directory. * by linking to the absolute path in
moc_qextserialport.cpp, which seemed to get rid of it, however it draws up
these now: 

*2>build\x\QExtSerialPort\src\moc_qextserialport.cxx(97): error C2027: use
of undefined type 'QextSerialPortPrivate'
2>  QExtSerialPort/src/qextserialport.h(167) : see declaration of
'QextSerialPortPrivate'
2>build\x\QExtSerialPort\src\moc_qextserialport.cxx(97): error C2227: left
of '->_q_canRead' must point to class/struct/union/generic type*

All these errors stem from a class in qextserialport_p.h (Recall:
QExtSerialPort/src/qextserialport_p.h(0): Note: No relevant classes found.
No output generated. still shows up),

So I guess the question is still how do I get the compiler to read these
files? And why is it not reading them? 

This is how the CMakeLists.txt file looks as it is right now:


*PROJECT(CppSampleQt01)
FIND_PACKAGE(Qt4 REQUIRED)

FIND_LIBRARY(SIMPLONLIB lv.simplon lib)
FIND_LIBRARY(SIMPLONIMGPROC lv.simplon.imgproc lib)

	#Check syntax for this. QExt... may need to be wrapped in parentheses. 
	LIST(APPEND QExtSerialPort_SOURCES

	#  add_definitions(-DWINVER=0x0501) # needed for mingw (dbt business??

endif(WIN32)

	LIST(APPEND QExtSerialPort_SOURCES

endif (OSX)

ADD_DEFINITIONS(${QT_DEFINITIONS})


INCLUDE_DIRECTORIES(${CMAKE_CURRENT_BINARY_DIR}

ADD_EXECUTABLE(CppSampleQt01 ${CppSampleQt01_SOURCES}

				${CppSampleQt01_RESOURCES_RCC})

TARGET_LINK_LIBRARIES(CppSampleQt01 ${QT_LIBRARIES} ${SIMPLONLIB}
${SIMPLONIMGPROC})
*

Once again, thank you guys!
