After extracting the tarball in a temporary directory we copy the tree
to the destination directory. The 'cmake -E copy_directory' command
does not preserve file timestamps, so we use file(COPY) instead.
The add_external_project function separates its arguments with ';'
separators, so previously no command line argument could contain one.
When specifying CMAKE_ARGS, some -D argument values may need to contain
a semicolon to form lists in the external project cache.
This adds add_external_project argument LIST_SEPARATOR to specify a list
separator string. The separator is replaced by ';' in arguments to any
command created to drive the external project. For example:
add_external_project(...
LIST_SEPARATOR ::
CMAKE_ARGS -DSOME_LIST:STRING=A::B::C
...)
passes "-DSOME_LIST:STRING=A;B;C" to CMake for the external project.
This fixes the get_configure_command_id function to not mistake
CONFIGURE_COMMAND values that run "cmake -P" or "cmake -E" for a CMake
project configuration. These values just help run scripts.
This creates function 'add_external_project_step' to centralize creation
of external project steps. Users may call it to add custom steps to
external project builds.
The add_external_project function parses its arguments and puts them in
properties of the target it creates. This factors out implementation of
the behavior for use by other functions in the module.
The patch step runs parallel to the update step since it does not make
sense to have both. Configuration of the step requires specification of
a PATCH_COMMAND argument to add_external_project.
This rewrites the keyword/argument parsing and handling in the
AddExternalProject module to use arguments more literally:
- The strict keyword-value pairing is gone in favor of keywords with
arbitrary non-keyword values. This avoids requiring users to escape
spaces and quotes in command lines.
- Customized step command lines are now specified with a single
keyword <step>_COMMAND instead of putting the arguments in a
separate entry (previously called <step>_ARGS).
- Build step custom commands now use VERBATIM mode so that arguments
are correctly escaped on the command line during builds.
This creates global property RULE_MESSAGES which can be set to disbale
per-rule progress and action reporting. On Windows, these reports may
cause a noticable delay due to the cost of starting extra processes.
This feature will allow scripted builds to avoid the cost since they do
not need detailed information anyway. This replaces the RULE_PROGRESS
property created earlier as it is more complete. See issue #8726.

its system include directories. These are catched in CMakeSystemSpecificInformation.cmake
(only with the Eclipse generator) and then written by the Eclipse generator
in the Eclipse project file. This way Eclipse can find the standard headers

Not sure CMakeSystemSpecificInformation.cmake is the best place to do this.

This teaches AddExternalProject to run "$(MAKE)" for build and install
steps of CMake-based external projects when using a Makefile generator.
It allows the external project to participate in a parallel make invoked
on the superproject.
This uses the get_property command to simplify property lookup in the
AddExternalProject module. It distinguishes for build and install
argument properties the cases of unset and set to empty.
This creates variable CMAKE_<LANG>_IMPLICIT_INCLUDE_DIRECTORIES to
specify implicit include directories on a per-language basis. This
replaces the previous platform-wide variable. It is necessary to
avoid explicit specification of -I/usr/include on some compilers
(such as HP aCC) because:
1.) It may break ordering among system include directories defined
internally by the compiler, thus getting wrong system headers.
2.) It tells the compiler to treat the system include directory
as a user include directory, enabling warnings in the headers.
See issue #8598.
We used to suppress generation of -I/usr/include (and on OSX also
-I/usr/local/include). This behavior seems to cause more trouble than
it's worth, so I'm removing it until someone encounters the original
problem it fixed. See issue #8598.
