[cmake-developers] New feature, git access

[Pau Garcia i Quiles]

Hello,

I have implemented an EXTRACT_COMMAND for ExternalProject_Add.

It is useful in case you are downloading a file that CMake does not know
how to extract, but you do (e. g. NSIS installers that can be extracted
without installation, self-extracting ZIP files, etc).

Code is here for now:

https://elpauer.assembla.com/code/elpauercmake/git/nodes/epa_extract_command

A test has been implemented. Run "git diff master epa_extract_command" to
see the changes, which are not really that important.

The reason I implemented this feature is I want to download and use the
Microsoft HTML Help Compiler. As it's a self-extracting ZIP file with a
.exe extension, ExternalProject refused to download it because it didn't
know how to extract it.

I have applied for git access but I am not sure whether I have done that
correctly. Specifically, I don't understand the "...After you have been
invited..." in http://www.cmake.org/Wiki/CMake/Git/Account#Git (who would
know I need an invitation!? where should I request such an invite?)

Please tell me if I need to do something more to get access to the staging
area of git://cmake.org.

Thank you
