Can you create a small example that shows the problem? Even a small
full example with the code you have below so I can better understand it.

Thanks, Andrew, Bill, and Zan! I'm not completely certain that
reinstalling Windows is the only or even the best solution, but once we
all moved our repositories into our root directories I have not found
another solution, even temporary. Of our six dev machines, it is a
recurring problem on two and has occurred once on a third. The other
three have never seen this problem.
I did some digging on Friday and found that the problem seems to be
connected to this call below to add all of our code files to a library
to be used an item in the add_executable() command for each of our targets.
foreach (code ${code_files})
get_filename_component (codeName ${code} NAME_WE)
add_library (${codeName} OBJECT
${code}
)
list(APPEND codelib $<TARGET_OBJECTS:${codeName}>)
endforeach()
If I remove that loop and add code_files instead of codelib to the
executables then the problem disappears, but this breaks most of the
functionality of my implementation of CMake, so this isn't a long-term
solution. Using the library call above I followed the file paths around
the script and printed them out at every step through the makefile
generation and never saw any incorrect paths, but then I called the
compiler and saw it error out.
The project uses "Unix Makefiles" to run on TI's gmake compiler 7.4.14.
I'm have been using CMake 3.5.2. I upgraded to 3.6.2 and continue to see
the same problem. I will move forward with looking into this library
issue but I'm sure what I expect to find.

Hello! I've been running into a frustrating issue on and off for
the past year. The project will build the source files correctly
but when it comes to linking the executables, I always get the
same error. The specific file varies, but the failure mode is
always the same. For example:
<Linking>
"C:\\Users\\User\\AppData\\Local\\Temp\\<six digit temp file>",
line xxx: error #10008-D: cannot find file
"C:/Repos/operatingsystem/CMakeFiles/nvm_validate_ierator.dir/os/nvm/nvm_validate_iterator.c.obj"
As you can see, the file path is missing a "t" in the first
occurrence of the word "iterator" and so that file definitely
does not exist. A file exists in the location with correct
spelling, but somehow that hardcoded path in that temporary file
has dropped a letter. The specific letter that gets dropped
varies along with which file is allegedly missing. We noticed
that requiring people to store the repository in their root
directory greatly cut down on the occurrence of this issue but
it is returning with more frequency as of late. Once it occurs
once, CMake builds are never successful again and the only way
that I have been able to completely clear the problem has been
to reinstall Windows and set up the build environment again.
This seems really, really strange. Have to reinstall Windows? What
about just using another build directory? It sure *seems* like
there's some problem in your CMakeFiles.txt where the way the
filepath is being constructed is incorrect. But I don't think
you've really provided enough information to determine the problem.
Where does the name of the object file come from?
