本文介绍了在使用CMake构建项目时遇到的关于文件时间戳在未来导致的警告问题及其解决方法。此类警告通常由构建机器的时钟与源文件的时间戳不同步引起，可能导致构建不完整。文章提供了具体的步骤来解决这一问题。

问题：

[ 92%] Building C object CMakeFiles/dyna.x.dir/mystrings/StrEdit.c.o
[100%] Building C object CMakeFiles/dyna.x.dir/mystrings/mystring.c.o
Linking C executable dyna.x
make[1]: Warning: File `StrEdit.c' has modification time 36 s in the future
make[2]: warning: Clock skew detected. Your build may be incomplete.

原因：
in regards to the below warning...
Warning message: Clock skew detected. Your build may be incomplete.

These warnings can occur when the clock on the build machine is out of sync with the timestamps on the source files. Other errors, apparently unrelated but in fact caused by the clock skew, can occur along with the clock skew warnings. These secondary errors may tend to obscure the fact that the true root cause of the problem is an out-of-sync clock. For example, an out-of-sync clock has been known to cause an old version of javac to be used to compile some files, resulting in errors when the pre-1.4 compiler ran across the new assert keyword in the 1.4 source code.
If you see these warnings, reset the clock on the build machine, run "gnumake clobber" or delete the directory containing the build output, and restart the build from the beginning.

解决：

find . -type f | xargs -n 5 touch
make clean
make
