Hello all,

  Recently I tried to build the latest stable version of curl
(7.20.0) with using cmake. To my surprise, the build on windows
succeeded without any issues. Then I tried the cmake build on
OpenSolaris, and the build failed.

After some investigation I discovered the following:
1. CMake build uses 'curlbuild.h' file that comes with the
   distribution. This means that, in essence, curl build is just the
   same as non-configure builds.
2. Tests that CMake does are not used afterwards; curlbuild.h that
   CMake generates is not included. Besides, the generated
   curlbuild.h file contains incorrect definitions (format strings
   not enclosed in double quotes, etc).

So I fixed the cmake build so that it generates a correct curlbuild.h.
I also had to fix "curl/curl.h" file, because its original way of
including "curlbuild.h" does not work with out-of-source build
which is used by cmake.

So now the modified version builds nicely on the following OSes:
- Windows32 (MS Visual Studio 2005 and 2008)
- Ubuntu linux (gcc 4.2)
- Slackware 12
- OpenSolaris (SunStudio 12)
- FreeBSD 7.0

The patch is attached (I hope git will have no problems applying it:).

Note that there are still some issues with the cmake build system:

- Although in-source builds (as 'configure' does) are still allowed,
  the curlbuild.h file that comes with the distro is not replaced with
  a cmake-configured one. Perhaps we should issue a warning (or even
  an error) when a user tries to build curl with cmake in-source.

- Before defining any of the CURL_PULL_* variables, cmake build should
  do more tests. I have done the checks in a very striaghtforward way:
  basically, if the headers were found during checks, the
  corresponding CURL_PULL_*_H variable gets defined.
