CMAKE工具链包括多个文件

Question

由于无关紧要的原因，我希望能够将多个文件包括在工具链文件中。假设我的工具链包含以下：

message(STATUS "file1 is ok")
include(./build/file2)

File2包含标识行：

message(STATUS "file2 is ok")

cmakelists.txt包含：

cmake_minimum_required (VERSION 2.8.8)
project (pro)
message(STATUS "cmakelists.txt is ok")

我使用以下命令称其为：

cmake -DCMAKE_TOOLCHAIN_FILE=../../build/file1 ../../

现在，我希望以下输出：

-- file1 is ok
-- file2 is ok
-- cmakelists.txt is ok

但是我明白了：

-- file1 is ok
-- file2 is ok
-- file1 is ok
-- file2 is ok
-- The C compiler identification is Clang 5.0.0
-- The CXX compiler identification is Clang 5.0.0
-- Check for working C compiler: /usr/bin/cc

  It fails with the following output:

Cmake不仅两次打印信息，还声称在此之后第三次找不到文件。

有任何想法吗？

Answer 1

不仅cmake打印两次信息

这是正常的：在配置期间，执行了几个步骤。在每个步骤上，工具链文件使用的文件。

它还声称它在此之后的第三次找不到包含的文件。有任何想法吗？

提供绝对路径。
