Use keyword signature in CMakeLists

[lynzrand]

CMake reported an error when compiling a project using this repository as a dependency:

CMake Error at include/quickjs/CMakeLists.txt:55 (target_link_libraries):
  The plain signature for target_link_libraries has already been used with
  the target "qjs".  All uses of target_link_libraries with a target must be
  either all-keyword or all-plain.

  The uses of the plain signature are here:

   * include/quickjs/CMakeLists.txt:51 (target_link_libraries)

It seems like the error was caused by this like in CMakeLists.txt, which uses the plain (no PUBLIC/PRIVATE) target_link_libraries statement.

quickjs-build/CMakeLists.txt

Line 51 in a516a78

target_link_libraries(qjs atomic)

Changing it to target_link_libraries(qjs PRIVATE atomic) seems to fix the problem.

• Arch Linux in WSL2 (5.10.60.1-microsoft-standard-WSL2)
