Ok, I assume that means you are actually looking at CMakeError.log and 
not the output you get from CMake concerning your own project's 
configuration run.
try_compile() runs aren't necessarily meant to succeed but rather their 
outcome is used in conditionals which may or may not have fatal outcomes 
for your actual project.


If a fatal diagnostic is produced based on such a conditional it would 
be visible in CMake's direct output (with file and line information) not 
CMakeError.log.
You only need to look at CMakeError.log to understand why a 
try_compile() did not succeed even though you would have expected it to.


The CMakeLists.txt where the error comes from in your failing 
try_compile() is generated and temporary so you will not find it in your 
own sources.

I can confirm this works with cmake version 3.9.0 on Windows 10

D:\tmp\cmake-location\build>cmake ..
-- Building for: Visual Studio 15 2017
CMake Error at foo/CMakeLists.txt:1 (add_executable):
  add_executable called with incorrect number of arguments

-- Configuring incomplete, errors occurred!
See also "D:/tmp/cmake-location/build/CMakeFiles/CMakeOutput.log".

Do you have a minimal reproducible example for that behaviour?


e.g. given:

   cmake_minimum_required(VERSION 2.8.0)

project(Foo NONE)

file(WRITE foo/CMakeLists.txt "add_executable()")

add_subdirectory(foo)


I get:
