With the Makefile generator one can use `cd $subdir; make install` to build and
install targets associated with a given subdirectory. This is not possible to
do with the Ninja generator since there is only one `build.ninja` file at the
top of the build tree. However, we can approximate it by allowing one to run
`ninja $subdir/install` at the top of the tree to build the targets in the
corresponding subdirectory and install them.
This also makes sense for `test`, `package`, and other GLOBAL_TARGET targets.
It was already done for `all` by commit v3.6.0-rc1~240^2~2 (Ninja: Add
`$subdir/all` targets, 2016-03-11).
In cmGlobalNinjaGenerator::AppendTargetOutputs we previously
handled GLOBAL_TARGET outputs specially in order to avoid adding
directory components to the output. However, this is not necessary
because cmNinjaTargetGenerator::New already filters out copies of
these targets that are not at the top level. Instead we can simply
follow the same output computation code path as UTILITY targets.
CMake used to put all header search paths into HEADER_SEARCH_PATHS
attribute. Unfortunately this attribute does not support to declare
a search path as a system include.
As a hack one could add a -isystem /path to the cflags but then include
ordering is not deterministic. A better approach was chosen with this
patch by not filling HEADER_SEARCH_PATHS at all and to populate
the C, C++, and Fortran flags directly. The include paths used by
Xcode should be now identical to the ones used by Unix Makefiles and
Ninja generator.
The Numerical Algorithms Group (NAG) Fortran compiler documents -PIC for
position-independent code and does not have a separate option for PIE.
We added `-PIC` for PIC in commit v2.8.11~174^2 (NAG: Use -PIC for
Fortran position-independent code, 2013-02-18). Follow up for PIE.
Closes: #16236
The implementation of `install(EXPORT)` generates files into a staging
directory for later installation. We use the full install destination
in the path to the staging directory to avoid collisions. In order to
avoid exceeding maximum path lengths (especially on Windows) we compute
a hash of the install destination when it is too long. Fix this logic
to account for the length of the file name(s) when deciding whether to
switch to the hashed name.

When using `grep` to filter the output, add the `-a` flag to tell
it never to treat the output as binary. Otherwise when LANG != C
in the environment the non-ascii text may break the filter.
In case of long '<command> <args...>' the description text is wrapped
and indented on the next line.
Avoid taking these lines into account by explicitly requiring the third
character to be a non-space.
The `CMAKE_<LANG>_SIMULATE_ID` variables are not set to "GNU" for a
GNU-like Clang compiler on Windows. They are only set to "MSVC" for a
MSVC-like Clang. Revise our response file format selection accordingly.
