Hi,
I'm having a project here where cmake refuses to recognize the "COMPONENT"
option for the install() command for certain targets.
Within the project there are several subdirs, the top-level CMakeLists.txt
has a component-install rule like this:
INSTALL(DIRECTORY ${PROJECT_BINARY_DIR}/doc/html DESTINATION
share/doc/myapp COMPONENT documentation)
which generates the expected output in the cmake_install.cmake file.
However several subdirectories contain executable targets for which the
cmake_install.cmake file uses the "Unspecified" component. The executable
target files look like this:
SET(SOURCES
main.cpp object.cpp)
SET(MOCABLES
object.h)
QT4_WRAP_CPP(MOC_SOURCES ${MOCABLES})
ADD_EXECUTABLE(myapp ${SOURCES} ${MOC_SOURCES})
TARGET_LINK_LIBRARIES(myapp ${QT_LIBRARIES})
# Installation
INSTALL(TARGETS myapp RUNTIME DESTINATION bin
ARCHIVE DESTINATION lib
LIBRARY DESTINATION lib
COMPONENT applications)
I can't seem to find a reason for this misbehaviour using cmake --trace or
cmake --debug-output. Are there any other ways (short of patching +
compiling cmake) to find out what goes wrong here? And if not, can someone
give me a hint where to start patching?
I'm using cmake 2.8.11.2 on Debian/GNU Linux.
In a very small example with just an executable target in a single cmake
file everything works fine, but minimizing the real codebase is quite a bit
harder than I thought.
Andreas
