[CMake] Finding all the libraries except for one located in the last path dir

Tue Apr 5 17:37:34 EDT 2016

I resolved this using the option OUTPUT_STRIP_TRAILING_WHITESPACE in execute_process(). https://cmake.org/cmake/help/v3.0/command/execute_process.html I had not seen it.

Sorry for the spam, but I found out that there is a line break added by CMake

execute_process(COMMAND bash "../grab_libraries.sh" "lib_dirs" "${METHOD}" OUTPUT_VARIABLE lib_dirs)

grab_libraries.sh is located in the same folder than CMakeLists.txt and I call cmake .. from a build folder inside the same folder than CMakeLists.txt . The output for the script ./grab_libraries.sh is:

/usr/lib;/lib;/usr/lib64;/usr/local/tools/vtk-6.1.0/lib;/g/g92/miguel/petsc-3.6.2/miguel-opt/lib;/usr/local/tools/openmpi-intel-1.8.4/lib;/usr/local/tools/ic-14.0.174/composer_xe_2013_sp1.3.174/compiler/lib/intel64;/usr/lib/gcc/x86_64-redhat-linux/4.4.7;/g/g92/miguel/code/libmesh_2D/lib;

with no line break, whereas the output variable lib_dirs:

message(${lib_dirs})

/usr/lib/lib/usr/lib64/usr/local/tools/vtk-6.1.0/lib/g/g92/miguel/petsc-3.6.2/miguel-opt/lib/usr/local/tools/openmpi-intel-1.8.4/lib/usr/local/tools/ic-14.0.174/composer_xe_2013_sp1.3.174/compiler/lib/intel64/usr/lib/gcc/x86_64-redhat-linux/4.4.7/g/g92/miguel/code/libmesh_2D/lib

does have a line break and also the semicolons are removed. What’s happening here and how can I get rid of that?

Thanks

Miguel

My apologies, the previous error was because of a trailing whitespace. Although I would still like to know why the terminal variable

/usr/lib;/lib;/usr/lib64;/usr/local/tools/vtk-6.1.0/lib;/g/g92/miguel/petsc-3.6.2/miguel-opt/lib;/usr/local/tools/openmpi-intel-1.8.4/lib;/usr/local/tools/ic-14.0.174/composer_xe_2013_sp1.3.174/compiler/lib/intel64;/usr/lib/gcc/x86_64-redhat-linux/4.4.7;/g/g92/miguel/code/libmesh_2D/lib;

is transformed into

/usr/lib/lib/usr/lib64/usr/local/tools/vtk-6.1.0/lib/g/g92/miguel/petsc-3.6.2/miguel-opt/lib/usr/local/tools/openmpi-intel-1.8.4/lib/usr/local/tools/ic-14.0.174/composer_xe_2013_sp1.3.174/compiler/lib/intel64/usr/lib/gcc/x86_64-redhat-linux/4.4.7/g/g92/miguel/code/libmesh_2D/lib

Hello

I am calling find_library in a loop, using the same variable for HINTS. This variable (lib_dirs) is set using a script, and when I simply print it using message(), I obtain this output:

message(${lib_dirs})

/usr/lib/lib/usr/lib64/usr/local/tools/vtk-6.1.0/lib/g/g92/miguel/petsc-3.6.2/miguel-opt/lib/usr/local/tools/openmpi-intel-1.8.4/lib/usr/local/tools/ic-14.0.174/composer_xe_2013_sp1.3.174/compiler/lib/intel64/usr/lib/gcc/x86_64-redhat-linux/4.4.7/g/g92/miguel/code/libmesh_2D/lib

The variable lib_dirs is the output variable of a script that I call using execute_process(). The actual script output (in the terminal) is

/usr/lib;/lib;/usr/lib64;/usr/local/tools/vtk-6.1.0/lib;/g/g92/miguel/petsc-3.6.2/miguel-opt/lib;/usr/local/tools/openmpi-intel-1.8.4/lib;/usr/local/tools/ic-14.0.174/composer_xe_2013_sp1.3.174/compiler/lib/intel64;/usr/lib/gcc/x86_64-redhat-linux/4.4.7;/g/g92/miguel/code/libmesh_2D/lib;

but cmakes removes all the semicolons and puts them all together, why?

Now when I call find_library() for several libraries, I can find them all except the one located in /g/g92/miguel/code/libmesh_2D/lib, why?

Thanks

Miguel
