Stephen Kelly ca5d990f02 Help: Add a manual for compiler feature control.
Link to it from the documentation of related properties, variables
and commands.

Extend the cmake-developer(7) documentation with notes on
extending feature support for compilers.

Rolf Eike Beer 0645eedb71 FindQt[34]: Prefer matching versioned tool names
After finding qmake we search in QT_BINARY_DIR for the other Qt tools.
Try all versioned executable names before trying the plain executable name.
This makes it much more likely that if 2 different major versions are installed
in the same prefix CMake will be able to detect a proper set of tools.

Daniele E. Domenichelli 1890c668e9 Keep cmake_minimum_required calls in sync with current version
Update cmake_minimum_required calls in CMakeLists.txt in Modules and in
CMakeLists.txt generated by other modules, so that they are always in
sync with current CMake version.
2014-05-19 16:55:12 +02:00
Daniele E. Domenichelli 81a3f22882 Do not change minimum required version in modules
Some modules change CMake minimum required version when they are
included. For example:

  cmake_minimum_required(VERSION 2.8.12)
  message("${CMAKE_MINIMUM_REQUIRED_VERSION}")
  include(CheckTypeSize)
  message("${CMAKE_MINIMUM_REQUIRED_VERSION}")

will produce the following output:

  2.8.12
  2.6

This patch ensures that when you include a CMake module the minimum
required version and the policies set are left unchanged.

Fixes Issue #14864

James Bigler 6ad14c71bb FindCUDA: Use CUDA_NVCC_FLAGS* for separable compilation
Previously when linking the intermediate link file for separable compilation
the CUDA_NVCC_FLAGS* were not used.  This caused tremendous confusion when
using this feature, and I consider it to be a bug.  This change should fix
this.

Stephen Kelly f6f1095413 Features: Use the features symbol in the feature-test compile.
Clang discards the entire string if it is not used, removing
the ability to read the features from the compiled binary. That
is prevented by using the symbol.

GNU with -O3 also discards the string, so use the string in a
way which is determined by a runtime value (argc) to prevent
it being discarded.

Stephen Kelly e0890d03a4 Features: Extend concept to C language.
Add properties and variables corresponding to CXX equivalents.

Add features for c_function_prototypes (C90), c_restrict (C99),
c_variadic_macros (C99) and c_static_assert (C11). This feature
set can be extended later.

Add a <PREFIX>_RESTRICT symbol define to WriteCompilerDetectionHeader
to conditionally represent the c_restrict feature.

Stephen Kelly 62a4a67dc5 Add the WriteCompilerDetectionHeader module.
Provide a function to write a portable header to detect compiler
features.  Generate a preprocessor #error for unknown compilers
and compiler versions whose features are not yet recorded.  This
error condition might be relaxed in the future, but for now it
is useful for verification of expectations.

file compiles, but it is documented as available first in GNU 4.8.

Mikołaj Siedlarek 1bed75a590 OS X: Use -iframework for system framework directories
Just like -I flag has its -isystem counterpart which marks an include
directory as a system directory and prevents unwanted warnings, on Apple
systems there is -iframework -- a system directory replacement for -F.
Use this flag to implement include_directories(SYSTEM) for frameworks.
