We'd like to use a consistent checksum scheme everywhere so that we can:
a) incorporate archive checksums into our specs and have a
consistent hashing algorithm across all specs.
b) index mirrors with a consistent type of checksum, and not one that
is dependent on how spack packages are written.
- [x] convert existing md5, sha224, sha512, sha1 checksums to sha256
- remove the old LGPL license headers from all files in Spack
- add SPDX headers to all files
- core and most packages are (Apache-2.0 OR MIT)
- a very small number of remaining packages are LGPL-2.1-only
- Adds v1.3.0 and v1.4.0
- List explicit CMake version dependency (from Benchmark CMake files)
- Disable the building of tests. Starting in v1.4.0 this introduced a dependency on GoogleTest
Tested by building all versions on macOS High Sierra
Adds a the latest version of gBenchmark, release 1.2.0.
This is the first gBenchmark version with proper
[CMake config package installs](https://github.com/google/benchmark/issues/363).
This is important for dependencies building against it, such as gRPC.
* Add universal build_type variant to CMakePackage
* Override build_type in some packages with different possible values
* Remove reference to no longer existent debug variant
* Update CBTF packages with new build_type variant
* Keep note on build size of LLVM
* gBenchmark: Development Package
Add the development version (master branch) of `gBenchmark`
* gBenchmark: Remove Duplicate
Remove duplicate `gbenchmark` library
and keep its patch to remove the shipped
