Bug 77928 – [CMAKE] Use *bin* and *lib* directories for executable and libraries

• Status: RESOLVED
• Resolution: FIXED
• Component: New Bugs

[Gyuyoung Kim]

In cmake build system, shared libraries are being built in source directory. It is better to set a common place to maintain built libraries. In addition, test bot uploads libraries with test result. Thus, I need a common place for all libraries in order to upload all libraries.

AFAIK this isn't necessary. CMake takes care of creating directories when needed.

Why "libs", isn't "lib" more common for such a directory (like "bin" is more common than "Programs")?

Ok, I fix it. Frankly, above code is not necessary. I added it to create directory more correctly as *Programs*.

QT port is using *bin* and *lib*. By comparison, GTK port is using *Programs* and *.libs*. I think we have to get agreement from port maintainers(Wince, Blackberry and EFL). I agree. :-)

There is also the common "/usr/bin" and "/usr/lib".

New patch is submitted. I set bin and lib directory for executable and library.

Daniel reviews this patch, I think blackberry port also agrees with this change.

IMHO you should use sth. like:
SET(CMAKE_ARCHIVE_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/lib)
SET(CMAKE_RUNTIME_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/bin)
SET(CMAKE_LIBRARY_OUTPUT_DIRECTORY ${CMAKE_RUNTIME_OUTPUT_DIRECTORY})
in the root CMakeLists.txt, instead of adding this to the different executeable names.

When we set CMAKE_ARCHIVE_OUTPUT_DIRECTORY, static libraries are also moved to lib directory. I think it is better to move shared libraries to lib directory only.

Why don't we use below setting ?

SET(CMAKE_LIBRARY_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/lib)
SET(CMAKE_RUNTIME_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/bin)

It's ok for me too. I only want to avoid the "'Programs/' prefix" on the different targets. ;-)

I don't have a CMake build at the moment. I assume that these directories are created by CMake in the directory CMAKE_BINARY_DIR.

Yes, right. *.so files are created in CMAKE_BINARY_DIR/lib and excutables are created in CMAKE_BINARY_DIR/bin.
