what's the the correct way to do the following:
1) Compile and install a binary foo to /usr/bin/foo
2) Create a link /usr/bin/bar -> /usr/bin/foo
3) On "make uninstall" remove /usr/bin/foo and /usr/bin/bar
For 1+2, I used
SET_TARGET_PROPERTIES(foo PROPERTIES POST_INSTALL_SCRIPT make_links.cmake)
In CMake 2.4 you can do
ADD_EXECUTABLE(foo foo1.cxx ...)
INSTALL(TARGETS foo DESTINATION bin)
INSTALL(CODE "
EXECUTE_PROCESS(
COMMAND \${CMAKE_COMMAND} -E remove \${CMAKE_INSTALL_PREFIX}/bin/bar
COMMAND \${CMAKE_COMMAND} -E create_symlink foo
\${CMAKE_INSTALL_PREFIX}/bin/bar
)
LIST(APPEND CMAKE_INSTALL_MANIFEST_FILES
\${CMAKE_INSTALL_PREFIX}/bin/bar)
")
The INSTALL(CODE ...) command puts code directly into the install
script. Note that by escaping the dollar signs '\$' they are placed
literally into the script which will evaluate the variables at install
time. The CMAKE_INSTALL_MANIFEST_FILES variable maintains a list of
installed files.
Use this with care...the code will still try to run on Windows platforms
where there are no symlinks and the executables have a .exe extension.
