Since commit "Provide unix-sytle command line parsing" (2009-07-13) the
reference to KWSYS_C_HAS_PTRDIFF_T in System.c has been meaningless
because the macro was never passed to the compiler!
ldd can return "not found" and we need to handle it correctly.
In that case, we extract only the name of the library instead of trying for its full path.
Some zlib.h files have ZLIB_VERSION "1.2.3.3" with 4 numbers instead of 3.
The regex is changed to grab the first 3 numbers.
It was slow because if it failed to find that string near the top of the file,
where it usually is, it would read the entire file.
I naively assumed in my previous commit that the Convert call
would correctly convert a relative path file name correctly
relative to the makefile's current output directory. It actually
converts it relative to the process's current working directory.
So it would be different depending on how you launched cmake-gui.
This commit ensures that the generated files are always the same
by starting with a full path to begin with, based on the makefile
GetCurrentOutputDirectory method.
Git's diff-tree format has no '\n'-terminated blank line at the end of
its commit message body block if there are no diff lines. Instead the
message body is terminated by '\0' and there is no diff section. Teach
CTest to parse the format in this case.
Avoid issues with two external projects trying to extract two
separate trees at the same time into the same location. Should
fix the sporadically failing ExternalProject test on the dashboards
for parallel builds.
In version 3.0 of the CUDA toolkit when building code for emulation, you need to link
against a new version of the cuda run time library called cudartemu. This CL adds a check
for the new library and uses it when present and in emulation mode. Note that this
library is not present in previous or subsequent versions of the CUDA toolkit.
If GIT_EXECUTABLE is not passed into the test, but the source
tree is a git checkout, then use GitCommand or UpdateCommand
from the ctest ini file to set its value. Presumably, a dashboard
running the test suite had to have set this properly in order
to do the ctest_update step.
