For CMake's “install” command, what can the CO

问题:

I don't know what the argument COMPONENT of the install() command means, and I don't understand the CMake documentation for this. What is it in more detail?

What would an example be?

You can group installation targets into components, for example, "docs", "libs", "runtime", etc.

add_library(libone libone.c)
add_executable(one main1.c)
install(TARGETS libone one DESTINATION /somedir COMPONENT comp_one)

add_library(libtwo libtwo.c)
add_executable(two main2.c)
install(TARGETS libtwo two DESTINATION /somedir COMPONENT comp_two)

This makes it possible to run cmake -DCOMPONENT=comp_one -P {your_build_dir}/cmake_install.cmake to install only the libone library and the one executable. When you issue make install all components are installed.

There are three ways you can use the install command in CMake:

1. Install an executable

   INSTALL(TARGETS ExecutableTarget RUNTIME DESTINATION FOLDER_LOCATION)
   

2. Install a static library

   INSTALL(TARGETS StaticLibraryTarget ARCHIVE DESTINATION FOLDER_LOCATION)
   

3. Install dynamic library

   INSTALL(TARGETS SharedLibraryTarget LIBRARY DESTINATION FOLDER_LOCATION)
