llvm-mirror/lib/Fuzzer/test/DSO1.cpp
Marcos Pividori 5b36dac81c [libFuzzer] Fix test with shared libraries on Windows.
We need to set BINARY_DIR to: ${CMAKE_BINARY_DIR}/lib/Fuzzer/test , so the dll
is placed in the same directory than the test LLVMFuzzer-DSOTest, and is found
when executing that test.
As we are using CMAKE_CXX_CREATE_SHARED_LIBRARY to link the dll, we can't modify
the output directory for the import library. It will be created in the same
directory than the dll (in BINARY_DIR), no matter which value we set to
LIBRARY_DIR. So, if we set LIBRARY_DIR to a different directory than BINARY_DIR,
when linking LLVMFuzzer-DSOTest, cmake will look for the import library
LLVMFuzzer-DSO1.lib in LIBRARY_DIR, and won't find it, since it was created in
BINARY_DIR. So, for Windows, we need that LIBRARY_DIR and BINARY_DIR are the
same directory.
