cmake_minimum_required() call is present this line can lead to an error as that

This version is generated by the Windows Visual Studio
project files for unknown reasons, but is required to
pick up the debug version of the library created by
current versions of Xerces-C.
Since commit v2.8.7~31^2 (HP: Drive shared library linking with compiler
front end, 2011-12-12) the C compiler is used to link shared libraries
instead of calling the linker directly, so linker options need to be
wrapped as -Wl,-foo instead of -foo.
The compiler version reported since commit v2.8.2~1018 (CTest-side
support for compiler name and compiler version, 2009-10-12) only
reported the version of the compiler used to build CMake, and only
if it defined "_COMPILER_VERSION". Instead use the version of
the compiler used to build the project CTest is testing.
By default Mercurial command "clone" will implicitly call "update" with
the "default" branch after downloading the cloned repository. However
ExternalProject_Add() always generates a second "update" command after
cloning with a tag which is either specified or "tip" (equivalent to
"default" by default). Therefore ExternalProject will first clone then
update to default branch then update to another specified branch if
provided. This leads to potentially very long clone operation (in
particular when the repository default branch contain subrepos) which
can lead to transaction abort triggered by the server.
Simply use "hg clone -U" to avoid the implicit update during clone.
Our following call to "hg update" will take care of updating anyway.
Protobuf 2.6.x and lower do not use CMake (cmake is usable in Protobuf
3.x) but provide legacy Visual Studio projects files. Search their
output directories in 64-bit builds.
The Fortran compiler version detection infrastructure added by commit
v3.3.0-rc1~436^2~9 (Fortran: Add infrastructure to detect compiler
version, 2015-02-17) forgot to update CMakeFortranCompiler.cmake.in to
save the compiler version persistently as we do already in
"CMake{C,CXX}Compiler.cmake.in". Add the missing line now.
As dumpbin.exe is no longer reliable for gcc libraries on MinGW because
it crashes on many common libraries like libgcc_s and libgfortran it is
now necessary too resort to using objdump for DLL dependency walking.
Using objdump has a secondary problem in that it generates a lot of
output for large libraries and causes fixup_bundle() to take many
minutes to process what took fractions of a second with
"dumpbin.exe /dependents".
Add a 'grep' pre-filter in the execute_process() command pipeline to
reduce this output to a minimum for a several orders of magnitude speed
up. If grep is not available just use the full output.
As there does not seem to be a reliable way of detecting MinGW, callers
of fixup_bundle() may have to set the variable gp_tool to "objdump" if
dumpbin.exe is installed on the build machine to stop it using the
broken MS dumpbin.exe for library dependency walking.
Since commit v2.8.5~121^2~2 (FindMPI: Handle multiple languages,
2010-12-29) we called the GetPrerequisites is_file_executable function
but passed the name of a CMake variable instead of its value. Therefore
the function has always failed and caused the search for the compiler
name to run even with an absolute path. Switch to using if(IS_ABSOLUTE)
instead and drop use of GetPrerequisites.
Since commit v2.4.0~4325 (...use gcc -shared, even for C++ libraries,
2003-03-13) we use the C compiler "gcc" to link C++ shared libraries
compiled with "g++". At the time "g++" did not know how to link shared
libraries correctly. This has long since been fixed so simply drop the
special case.
Since commit v3.1.0-rc1~564^2 (OS X: Use -iframework for system
framework directories, 2014-05-05) we test the version of Clang to see
if it supports -iframework. Fix the version test used for AppleClang
since it uses a different version scheme than upstream Clang.
Run our check for the '_' prefix using a bzip2 API function as declared
with a prototype in the real header file. This is needed in case the
function is provided in a DLL import library where the symbol name may
not match without proper markup from the header.
