* No longer need to patch CMake. Using CMAKE_CXX_FLAGS to include BLAS/LAPACK/MKL header files properly.
* Backport two patches to QMCPACK versions prior to 3.3.0: https://github.com/QMCPACK/qmcpack/pull/621, https://github.com/QMCPACK/qmcpack/pull/623
* Insufficient to include lapack_dir in CMAKE_CXX_FLAGS, CMAKE_C_FLAGS is also needed.
* Make patched Espresso a default variant instead of a hard dependency. This is easier on computer architectures where Espresso is hard to build.
* Fix patching with QE variant. Now using correct form of patch command.
* Add QMCPACK v3.4.0
* Backport patch to QMCPACK versions prior to 3.3.0: https://github.com/QMCPACK/qmcpack/pull/643
* Fix detection of blas and lapack: provide libraries/includes as
arguments to CMake rather than using CMake's auto-detection.
This includes a patch to QMCPACK's CMake files to refer to
Spack-built blas/lapack implementations. This also includes
special-case logic for the intel-mkl implementation of blas/lapack
* Break up unit tests and short tests. Only hard failure if the unit
tests fail, if short tests fail issue a warning only.
* Add QMCPACK 3.3.0, get rid of 3.0.0
