CMake variable names case sensitive?

How does CMake treat variable names? Are they case sensitive?

If I use FindFoo.cmake with

find_package(Foo)

can I use FOO_FOUND, Foo_FOUND and foo_FOUND?

Solution

  • CMake variables are case sensitive. See documentation.

    As a side note, commands are case insensitive, and their arguments are case sensitive. See wiki. Keywords like STATUS are case sensitive because they are arguments. Example:

    message(STATUS foo)
MESSAGE(status foo)

    outputs:

    foo
statusfoo

    the second marked as a warning (default message type).

    Still regarding case sensitivity, take also a look to the boolean variable section.
