How do I make CMake output into a 'bin' di

Question

I'm currently constructing a project with a plugin structure. I'm using CMake to compile the project. The plugins are compiled in separate directories. My problem is that CMake compiles and saves the binaries and plugins, dynamic libraries, in the directory structure of the source. How do I make CMake save the files in something like a ./bin directory?

Answer 1

$ cat CMakeLists.txt
project (hello)
set(EXECUTABLE_OUTPUT_PATH "bin")
add_executable (hello hello.c)

Answer 2

Use set(CMAKE_RUNTIME_OUTPUT_DIRECTORY "/some/full/path/to/bin")

Answer 3

Use the EXECUTABLE_OUTPUT_PATH CMake variable to set the needed path. For details, refer to the online CMake documentation:

CMake 2.8.8 Documentation

Answer 4

As to me I am using cmake 3.5, the below(set variable) does not work:

set(
      ARCHIVE_OUTPUT_DIRECTORY "/home/xy/cmake_practice/lib/"
      LIBRARY_OUTPUT_DIRECTORY "/home/xy/cmake_practice/lib/"
      RUNTIME_OUTPUT_DIRECTORY "/home/xy/cmake_practice/bin/"
)

but this works(set set_target_properties):

set_target_properties(demo5
    PROPERTIES
    ARCHIVE_OUTPUT_DIRECTORY "/home/xy/cmake_practice/lib/"
    LIBRARY_OUTPUT_DIRECTORY "/home/xy/cmake_practice/lib/"
    RUNTIME_OUTPUT_DIRECTORY "/home/xy/cmake_practice/bin/"
)

Answer 5

As in Oleg's answer, I believe the correct variable to set is CMAKE_RUNTIME_OUTPUT_DIRECTORY. We use the following in our root CMakeLists.txt:

set(CMAKE_ARCHIVE_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/lib)
set(CMAKE_LIBRARY_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/lib)
set(CMAKE_RUNTIME_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/bin)

You can also specify the output directories on a per-target basis:

set_target_properties( targets...
    PROPERTIES
    ARCHIVE_OUTPUT_DIRECTORY "${CMAKE_BINARY_DIR}/lib"
    LIBRARY_OUTPUT_DIRECTORY "${CMAKE_BINARY_DIR}/lib"
    RUNTIME_OUTPUT_DIRECTORY "${CMAKE_BINARY_DIR}/bin"
)

In both cases you can append _[CONFIG] to the variable/property name to make the output directory apply to a specific configuration (the standard values for configuration are DEBUG, RELEASE, MINSIZEREL and RELWITHDEBINFO).

English is not my native language; please excuse typing errors.

use this line config :
set(EXECUTABLE_OUTPUT_PATH ${PROJECT_SOURCE_DIR}/build/)
place your any CMakeLists.txt project.
this ${PROJECT_SOURCE_DIR} is your current source directory where project place .
and if wander why is ${EXECUTABLE_OUTPUT_PATH}
check this file CMakeCache.txt then search the key word output path,
all the variables define here , it would give a full explanation of the project all setting·
