eeaaffc find_package: Test error and warning messages in failure cases
52dffb9 Merge branch 'test-CMakeCommands' into find_package-improve-messages
d365104 find_package: Optionally warn when implicitly using Config mode
31ead5f find_package: Reject mixed use of MODULE- and CONFIG-only options
6d83083 find_package: mention requested version number in error message
9c39bbd find_package: add CONFIG mode keyword alias for NO_MODULE
f310f67 find_package: add MODULE mode to use only Find-modules
7d67dcf find_package: improve error message when no Find module is present
978d89b find_package: rename NoModule to UseFindModules

CMake Warning at MissingNormalWarnNoModuleOld.cmake:2 \(find_package\):
By not providing "FindNotHere.cmake" in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by "NotHere", but
CMake did not find one.
Could not find a package configuration file provided by "NotHere" with any
of the following names:
NotHereConfig.cmake
nothere-config.cmake
Add the installation prefix of "NotHere" to CMAKE_PREFIX_PATH or set
"NotHere_DIR" to a directory containing one of the above files. If
"NotHere" provides a separate development package or SDK, be sure it has
been installed.
