Ninja: Windows10 Filename longer than 260 characters

Currently using absolute paths causes this error on windows platforms, and the problem still exists.

This error does not exist when I abandon target_link_libraries(test01 ${LLVM_LIBS})

[cctv130]

When I set target test1 to be a static library and not a shared library, the project will compile successfully.

Note that the real problem here might be the command line size limitation on Windows. See https://learn.microsoft.com/en-us/troubleshoot/windows-client/shell-experience/command-line-string-limitation

The maximum length of the string that you can use at the command prompt is 8191 characters.

For static libraries lib.exe is called, and for dynamic libraries link.exe is called.

You can check in build.ninja file to see how big the command line for each case is.

Ninja is just running the commands that the generator gives to it. This issue belongs purely on the CMake side, and IMO should be closed here.

for the 260 char problem, see #1900

[cctv130]

The problem is that cmake got all the dynamic libraries and ninja didn't handle the parameters correctly. If I pass the parameters incorrectly, I get the same error.

@cristianadam If it is consistent with what you said, then the following error will appear
The command line is too long.
