CMake生成的Xcode項目不會編譯

我有一個在Mac上開發的C++項目。我可以通過命令行與忍者或gmake建立它沒有問題，但一旦我生成的Xcode項目失敗。CMake生成的Xcode項目不會編譯

該項目本身是一個靜態庫鏈接到命令行應用程序，運行googletest。

我得到的錯誤是，當涉及到構建最終的可執行文件時，Xcode說它找不到靜態庫。這是我的CMakeLists.txt：

說它無法找到.a文件。我顯然可以將它拖入Xcode，但我寧願讓CMake爲我做。 – ruipacheco

是的，我有CMake中的說明來生成文件。它是示例代碼中由STATIC命令生成的。 – ruipacheco

您不能使用Xcode生成器創建僅包含對象文件的庫。從documentation：

Some native build systems may not like targets that have only object files, 
so consider adding at least one real source file to any target that 
references $<TARGET_OBJECTS:objlib>.

它在那裏，我正在構建一個可執行文件。 – ruipacheco

我很抱歉，但我的代碼似乎與您的示例沒有任何區別。唯一的區別是我在創建可執行源文件的路徑時展開CMake變量。 – ruipacheco

這同樣適用於庫對象。 – ruipacheco
