When find_package(<externalPkg>) uses a find module Find<exteranlPkg>.cmake instead of a package config file <externalPkg>Config.cmake, the variable. <externalPkg>_DIR is not set. Therefore, it is best to not set <externalPkg>_DIR in the TriBITS-geneated <tplName>Config.cmake file since that is just confusing. NOTE: The case where TriBITS a FindTPL<tplName>.cmake module calls find_package(<externalPkg>) is the only a situation where this is the case. When one TriBITS TPL is calling find_dependency() on an upstream TriBITS TPL, the <upstreamDepTpl>_DIR variable is always set.
This allows configuring with: -D "CTEST_BUILD_FLAGS=-j<n> -k 9999999" and having these arguments work correctly.
This is needed in order to avoid namespace classes with downstream CMake projects that call find_package(CUDAToolkit) (e.g. like Nalu-Wind, see trilinos/Trilinos#10954). NOTE: This has matching changes in the downstream Trilinos TPL files FindTPLCUBLAS.cmake and FindTPLCUSPARSE.cmake. You can't use this updated TriBITS version with Trilinos without those matching Trilinos FindTPL<tplName>.cmake changes (see trilinos/Trilinos#10954).

I am going to allow this to merge so I can snapshot to Trilinos and get trilinos/Trilinos#10954 fixed. I will then set up for a post-merge review.
