sed語法，錯誤不匹配（或\\（

Question

嘗試從另一個cmake文件中使用sed在帶有＃的cmake文件中注釋掉“ cmake_policy（SET CMP0022”）。嘗試轉義（和空格，但以某種方式不正確。正確的語法是什么？

set(PATCH_CMP0022 "s/cmake_policy\\(SET\\ CMP0022/#cmake_policy(SET\\ CMP0022/")
sed ${PATCH_CMP0022} ${PATCH_FILE} -i

如果重要的話，這是我的整個cmake代碼塊...

if(NOT EXISTS ${NAME}-patch)
    message("--- Patching ${NAME} ---")
    set(PATCH_CMP0022 "s/cmake_policy\\(SET\\ CMP0022/#cmake_policy(SET\\ CMP0022/")
    message(${PATCH_CMP0022})
    set(PATCH_SOURCE_DIR "s/CMAKE_SOURCE_DIR/CMAKE_CURRENT_SOURCE_DIR/")
    set(PATCH_FILE "${NAME}-src/CMakeLists.txt")
    execute_process(
        COMMAND sed ${PATCH_CMP0022} ${PATCH_FILE} -i
        COMMAND sed ${PATCH_SOURCE_DIR} ${PATCH_FILE} -i
        COMMAND touch ${NAME}-patch
        WORKING_DIRECTORY ${PATH_LIB})
endif()

如果您的數據位於“ d”文件中，請嘗試最多處理3（）對，

 sed -E 's/.*\([^\)]+[^\)]*$|.*(\(.*){2}\)[^\)]*$|.*(\(.*){3}\)\)[^\)]*$/#&/'
