Fixes#10769
This updates the .headers property to include header subdirectories
for Python and Eigen (as is recommended by these packages).
#10623 updated the default behavior of .headers.directories to
exclude subdirectories (since this can cause clashes with system
headers). This broke some packages which depended on the old behavior
of .headers.directories: for example if you had
<package-prefix>/include/subdir/ex1.h, .headers.directories would
include <package-prefix>/include/subdir.
The environment modules package has been updated to include
versions up to 4.0.0. The url of the package and the homepage
have been updated accordingly.
The `spack bootstrap` command now builds version 3.2.10 of
the environment-modules package, and will do until #10708
is fixed.
* Make use of new QE multi-valued HDF5 variant interface
* Remove explicit CUDA dependency (which is handled by inheriting
from CudaPackage)
* Update cuda_arch unset variant check
libbeagle compiles against CUDA by default but no there is no mention
of it in the package recipe. This PR adds explicit cuda paths and
variants, and fixes the target architecture as well (for those who
don't have compute_13)
Serial HDF5 in serial QE only works in develop version. This adds
a conflict to the QE package to prevent Spack from trying to build
specs which don't satisfy this constraint.
This restores the use of Package.headers when computing -I options
for building a package that was added in #8136 and reverted in
#10604. #8136 used utility logic that located all header files in
an installation prefix, and calculated the -I options as the
immediate roots containing those header files.
In some cases, for a package containing a directory structure like
prefix/
include/
ex1.h
subdir/
ex2.h
dependents may expect to include ex2.h relative to 'include', and
adding 'prefix/include/subdir' as a -I was causing errors,
in particular if ex2.h has the same name as a system header.
This updates header utility logic to by default return the base
"include" directory when it exists, rather than subdirectories.
It also makes it possible for package implementers to override
Package.headers to return the subdirectory when it is required
(for example with libxml2).
