CMAKE_FIND_DEBUG_MODE

Added in version 3.17.

Print extra find call information for the following commands to standard error:

• find_program()

• find_library()

• find_file()

• find_path()

• find_package()

Output is designed for human consumption and not for parsing. Enabling this variable is equivalent to using cmake --debug-find with the added ability to enable debugging for a subset of find calls.

set(CMAKE_FIND_DEBUG_MODE TRUE)
find_program(...)
set(CMAKE_FIND_DEBUG_MODE FALSE)

Default is unset.
