CMP0087

install(CODE) and install(SCRIPT) support generator expressions.

In CMake 3.13 and earlier, install(CODE) and install(SCRIPT) did not evaluate generator expressions. CMake 3.14 and later will evaluate generator expressions for install(CODE) and install(SCRIPT).

The OLD behavior of this policy is for install(CODE) and install(SCRIPT) to not evaluate generator expressions. The NEW behavior is to evaluate generator expressions for install(CODE) and install(SCRIPT).

Note that it is the value of this policy setting at the end of the directory scope that is important, not its setting at the time of the call to install(CODE) or install(SCRIPT). This has implications for calling these commands from places that have their own policy scope but not their own directory scope (e.g. from files brought in via include() rather than add_subdirectory()).

This policy was introduced in CMake version 3.14. CMake version 3.14.7 warns when the policy is not set and uses OLD behavior. Use the cmake_policy() command to set it to OLD or NEW explicitly.

Note

The OLD behavior of a policy is deprecated by definition and may be removed in a future version of CMake.
