[CMake] find_file/find_path recursive

[Pablo Yanez Trujillo]

Hi

I've already read the online documentation but I don't find anything
about it. I'm want to use 'find_path'. I only have the installation
prefix of a project and I would want to search recursively in this
directory. I've thought of something like that:

set(ABC_INSTALL_PREFIX "" CACHE PATH "Install Prefix of abc project")

find_path(ABC_PACKAGE_FILE abc-config.cmake PATHS ${ABC_INSTALL_PREFIX}
NO_DEFAULT_PATH)

if(NOT ${ABC_PACKAGE_FILE})
  message(FATAL_ERROR "Could not find abc-config.cmake. Set
ABC_INSTALL_PREFIX properly.")
endif()

set(abc_DIR ${ABC_PACKAGE_FILE})
find_package(abc)

but this only works when the abc-config.cmake file is stored in
${ABC_INSTALL_PREFIX}. This is not the case, hence I would want to
search for it recursively in ${ABC_INSTALL_PREFIX}, but I don't know how
to manage it.

Is it actually posible to search recursively with find_path?

Pablo
