We use `LUA_INCLUDE_PREFIX` for the result of an internal `find_path`
call and unset the cache entry before each use. Unset a plain variable
of this name too in case it was set by project code. Otherwise the
`find_path` call may be skipped and the wrong value used, leading to
errors.
In commit v3.11.0-rc1~466^2 (Compiler/TI: Add support for depfile
generation for Ninja, 2017-10-16) the flag for C++ was added in a
variable with a typo in its name. Fix the spelling.
Issue: #17360
When the path containing the wxLibraries contains a "-L", a "string(REPLACE "-L" ...)
replaces the content and results in a wrong path. The regex fixes this.
FindZLIB accepts various names for zlib (e.g. "z", "zlib", ...) in
various search locations. Before this patch zlib ignored the priority
implied by the search locations and instead prioritized based on the
library name. Consequently ensuring the pick of a zlib from e.g. a
CMAKE_PREFIX_PATH was not possible if it didn't have the highest
priority name ("z").
This unexpected behavior led to bugs in third party projects (e.g.
https://github.com/Microsoft/vcpkg/issues/1939). A common way to
encounter the issue in the wild is on Windows with the popular
Anaconda python distribution which puts a "z.lib" in a lib/
subdirectory reachable from a bin/ path in PATH. From then on cmake
will always pick up this library instead of the one intended by the
user.
This patch adds the NAMES_PER_DIR option to the find_library calls made
by FindZLIB making it search each directory for all names before
considering lower priority directory names resolving these issues.
A new cache option named `CMake_MSVC_PARALLEL` is now available that can
be used to control the usage of [`/MP`][1] to the MSVC compiler. This
enables parallelized builds on a per-translation unit basis. To enable
`/MP`, specify value `ON` to the option. Using an integral non-zero
value will control the specific number of threads used with the `/MP`
option, as opposed to letting the toolchain decide for you.

The `LINK_ONLY` generator expression is used to represent private
dependencies of static libraries in their `INTERFACE_LINK_LIBRARIES`
property value. Fix evaluation of generator expressions during export
to support the `LINK_ONLY` genex. Extend the RunCMake.AndroidMK test
with a case for this.
When exporting `INTERFACE_LINK_LIBRARIES`, we must evaluate generator
expressions first, before expanding the `;` list, in case they contain
or generate semicolons.
