This CMakeLists.txt file was a bit broken.  Here follows an updated version:

<example ~/src/ui/CMakeLists.txt>
set(ui_HEADERS
        MainWindow.h++
        # some other headers 
)

set(ui_SOURCES
        MainWindow.c++
        # some other sources 
)

set(ui_FORMS 
        MainWindow.ui
        # some other forms
)

QT4_WRAP_CPP(ui_HEADERS_MOC ${ui_HEADERS})
QT4_WRAP_UI(ui_FORMS_HEADERS ${ui_FORMS})

add_library(ui STATIC ${ui_SOURCES} ${ui_HEADERS_MOC} ${ui_FORMS_HEADERS} )
</example>


Although this CMakeLists.txt file appears to be enough to create a static 
library, the build process still fails.  This time, the error is caused by 
not including the path to the header files generated by uic.  More 
precisely, the error message is as follows:

<error message>
 fatal error: ui_MainWindow.h: No such file or directory
</error message>


It appears that the solution to this problem is to include the path to the 
ui_*.h files that are generated by uic.  To do that, I've tried including 
${CMAKE_CURRENT_BINARY_DIR} and "${PROJECT_BINARY_DIR}/src/ui", to no 
success.

Does anyone happen to know how to include the directory where uic dumps the 
header files?


Thanks in advance,
