+  System introspection is still possible  while cross-compiling:

+        - system introspection (try-compile, try-run)
+        - HOST-TOOLS, why might be required
+            - Using Executables in the build created during the build

+
+    \begin{itemize}
+        \item Header existence: {\code{check\_include\_file()}}
+        \item Library existence: {\code{check\_library\_exists()}}

+        \item Supported type sizes: {\code{check\_type\_size()}}
+    \end{itemize}
+
+    CMake provides an API to write custom checks via:
+
+    \begin{itemize}
+        \item {\code{try\_compile()}}
+        \item {\code{try\_run()}}
+    \end{itemize}
+
+    With {\code configure\_file} you can generate a header file
+      enabling required code switches based on the checks.
