cmake报错替换

if(NOT MyHTML_BUILD_WITHOUT_THREADS OR NOT MyCORE_BUILD_WITHOUT_THREADS)
set(CMAKE_THREAD_PREFER_PTHREAD 1)
if (WIN32)
set(CMAKE_USE_WIN32_THREADS_INIT ON)

find_package(Threads REQUIRED)
if(NOT CMAKE_USE_PTHREADS_INIT)
message(FATAL_ERROR "Could NOT find pthreads (missing: CMAKE_USE_PTHREADS_INIT)")

测试

add_executable(example examples/myhtml/modify_and_serialize.c)
target_link_libraries(example ${PROJECT_LIB_STATIC})
