From 48b380c9613318b888473aa6f178d06de3f21e7e Mon Sep 17 00:00:00 2001 From: Craig Scott Date: Sun, 11 Sep 2022 17:54:57 +1000 Subject: FetchContent: Ignore EXACT for redirected find_package() calls When FetchContent_MakeAvailable() populates a dependency for which find_package() integration is enabled, all future calls to find_package() MUST succeed using the contents of the redirection directory. The generated config version file was not handling calls where the EXACT keyword was given, resulting in such calls rejecting the redirection directory's contents and continuing its search. It is not allowed to do that. Fix the generated file to also set PACKAGE_VERSION_EXACT to true so that calls with EXACT now accept it, as was originally intended.
