Perhaps somebody can give me some hints on this problem I have. I build a
project and install it in <path>/install with "make install". Then I do change
the installation prefix with
cmake -DCMAKE_INSTALL_PREFIX=<path>/install2 ../root_cmake/
and if I execute again "make install" it rebuilds basically every library of
the project. I have traced the dependency to the generated link.txt file,
which contains the link command. In one case the contents of the file is:
/usr/bin/c++ -fPIC -pipe -m64 -Wall -W -Woverloaded-virtual -fPIC -O2 -g
-shared -Wl,-soname,libCint.so -o ../../lib/libCint.so
CMakeFiles/Cint.dir/src/loadfile.o ../../lib/libCint_static.a -lpthread
-Wl,-rpath,::::::::::::::::::::::::::::
and in the other is:
/usr/bin/c++ -fPIC -pipe -m64 -Wall -W -Woverloaded-virtual -fPIC -O2 -g
-shared -Wl,-soname,libCint.so -o ../../lib/libCint.so
CMakeFiles/Cint.dir/src/loadfile.o ../../lib/libCint_static.a -lpthread
-Wl,-rpath,:::::::::::::::::::::::::::::
Notice the different number of colons in the -rpath settings. The first
question I have is what is the origin of these many colons in the rpath
settings? The second question, why is different when I choose another
installation directory. My CMake variables that control RPATH are the following:
first
CMAKE_INSTALL_RPATH -->/build/mato/ROOT/install/lib
CMAKE_INSTALL_RPATH_USE_LINK_PATH -->TRUE
CMAKE_SKIP_BUILD_RPATH -->FALSE
CMAKE_BUILD_WITH_INSTALL_RPATH -->FALSE
and later
CMAKE_INSTALL_RPATH -->/build/mato/ROOT/install2/lib
CMAKE_INSTALL_RPATH_USE_LINK_PATH -->TRUE
CMAKE_SKIP_BUILD_RPATH -->FALSE
CMAKE_BUILD_WITH_INSTALL_RPATH -->FALSE
