[CMake] restricting Qt include and library linking to 1 library/project
Hello,
My toplevel CMakeLists.txt looks like:
PROJECT(...)
CMAKE_MINIMUM_REQUIRED(VERSION 2.8)
# Openmp
FIND_PACKAGE(OpenMP)
IF(OPENMP_FOUND)
SET(CMAKE_CXX_FLAGS ${CMAKE_CXX_FLAGS} ${OpenMP_CXX_FLAGS})
ENDIF()
# Boost
FIND_PACKAGE(Boost)
IF(Boost_FOUND)
INCLUDE_DIRECTORIES(${Boost_INCLUDE_DIRS})
ENDIF()
# Qt
FIND_PACKAGE(Qt4 4.6.0 COMPONENTS QtCore QtGui QtOpenGL REQUIRED)
INCLUDE(${QT_USE_FILE})
INCLUDE_DIRECTORIES(AFTER ${CMAKE_CURRENT_SOURCE_DIR})
ADD_SUBDIRECTORY(common)
ADD_SUBDIRECTORY(lib1)
ADD_SUBDIRECTORY(lib2)
ADD_SUBDIRECTORY(lib3)
ADD_SUBDIRECTORY(main)
Using QT_USE_FILE includes Qt headers for all of common, lib1, lib2, lib3.
How can I include and link Qt only for lib3?
Lib3's CMakeLists.txt looks like:
ADD_LIBRARY(lib3 STATIC #cpps hpps ipps)
ADD_DEPENDENCIES(lib3 common)
TARGET_LINK_LIBRARIES(lib3 ${QT_LIBRARIES})
Rds,

Re: [CMake] restricting Qt include and library linking to 1 library/project
Hello,
Do find_package( Qt4 COMPONENTS ... ) from each subdir and use only
the components you need for each library.
Do not INCLUDE( ${QT_USE_FILE} ) in any case, just do an include_directories.
When linking, do not use the contain-all QT_LIBRARIES variable but the
individual library variables.
Assuming lib1 uses QtCore and QtNetwork:
find_package( Qt4 COMPONENTS QtCore QtNetwork REQUIRED )
include_directories( ${QT_QTCORE_INCLUDE_DIR} ${QT_QTNETWORK_INCLUDE_DIR} )
add_library( lib1 SHARED lib1_source1.cpp lib1_source2.cpp ... )
target_link_libraries( lib1 ${QT_QTCORE_LIBRARIES} ${QT_QTNETWORK_LIBRARIES} )
You'd do similar for lib2 and lib3 and the main CMakeLists.txt would
only contain something like:
project( blah )
add_directory( lib1 )
add_directory( lib2 )
add_directory( lib3 )
i. e. no find_package( Qt4 ...) in the main CMakeLists.txt [*]
[*] Actually you can do the find_package( Qt4 COMPONENTES
yourcomponents ) in the main CMakeLists.txt but then you need to
specify all the components required by all the directories below that
one in the hierarchy, which is more difficult to track.

target_link_libraries( lib1 ${QT_QTCORE_LIBRARIES}

Does this take care of both release and debug libraries?
Ie, in release build, it will include release libs and in debug debug libs?
Thanks for this,

Yes, it does. Take a look at FindQt4.cmake for the details.

Re: [CMake] restricting Qt include and library linking to 1 library/project
If you have multiple directories with different Qt dependencies, you can do:
find_package(Qt4 REQUIRED)
in the top directory,
then each sub directory can do something like
set(QT_USE_QTOPENGL 1)
include(${QT_USE_FILE})
But in your case, its only lib3, so just do it in that CMakeLists.txt file.

That's what I did at the end.
I did this:
FIND_PACKAGE(Qt4 4.6.0 COMPONENTS QtCore QtGui QtOpenGL REQUIRED)
INCLUDE_DIRECTORIES(${QT_INCLUDE_DIR} ${QT_QTCORE_INCLUDE_DIR}
${QT_QTGUI_INCLUDE_DIR})
MESSAGE(STATUS QT_QTCORE_LIBRARY=${QT_QTCORE_LIBRARY})
TARGET_LINK_LIBRARIES(plot $QT_QTCORE_LIBRARY)
The include dirs are set correctly, but I'm having trouble with
QT_QTCORE_LIBRARY.
This appears as :
QT_QTCORE_LIBRARY=optimized;C:/Progra~2/Qt/4.6.0/lib/QtCore4.lib;debug;C:/Pr
ogra~2/Qt/4.6.0/lib/QtCored4.lib
When I open the solution with vs2008, the Librarian doesn't show this
libraries as input.
Note the help for TARGET_LINK_LIBRARIES displays the syntax as:
target_link_libraries(target [item1 [item2 [...]]]
[[debug|optimized|general] item] ...)
There are no semicolons after the optimized|debug keywords, I wonder if by
not using QT_USE_FILE, QT_QTCORE_LIBRARY are others are set incorrecty.

If you open cmake-gui does and look at the Qt tab in Grouped View are
the debug libraries properly set?

Rds,
You probably meant ${QT_QTCORE_LIBRARY} instead of $QT_CORE_LIBRARY
What about this:
find_package(Qt4 4.6.0 COMPONENTS QtCore QtGui QtOpenGL REQUIRED)
include(${QT_USE_FILE})
...
target_link_libraries(plot ${QT_LIBRARIES})
The file pointed to by QT_USE_FILE sets up the current directory with include
directories and compile flags and sets up QT_LIBRARIES for the chosen
components.
You can do it on your own, but its more work.
