For example, in “7″ lines you had only created a static library. Hey! What about dynamic .so/.dll? What about macros for the library? What about installation and packaging, uninstallation?

What if you had been using 3rd part library that has pkg-config…
Wait a second… Accidentally I should use foreach loop to add all flags of this pkg-config library.

What if I use sockets… Let’s check for gethostbyname…

Build system should not be trivial for simple builds, it should be resonable, simple for complex builds…

Let’s check sizeof something? Does not work in cross-compilation builds (issue solved years ago in auto*)

Take a look on this: http://cppcms.svn.sourceforge.net/viewvc/cppcms/framework/branches/refactoring/CMakeLists.txt?revision=977&view=markup

How verbouse it is! Simple tasks require lots of headache!

CMake is reasonable working build system but it is so far from being called best…
