Starting in 3.14 ExternalProject the LOG_DIR option was added to control the location of log files. The documentation states that if STAMP_DIR is set, and not LOG_DIR than the log files are placed in the STAMP_DIR location. This is not the case, instead they are placed in the default STAMP_DIR location, and not the user provided location.

example cmake code:

cmake_minimum_required(VERSION 3.14.0)
include(ExternalProject)

externalproject_add(
    vtkm
    GIT_REPOSITORY "https://github.com/robertmaynard/vtk-m"
    GIT_TAG "bdcb76cadbf8a949473d6"
    INSTALL_DIR "${CMAKE_BINARY_DIR}/install"
    CMAKE_ARGS -DCMAKE_INSTALL_PREFIX=${CMAKE_BINARY_DIR}/install
    DOWNLOAD_DIR downloads
    SOURCE_DIR vtkm/src
    BINARY_DIR vtkm/build
    STAMP_DIR vtkm/stamp
    LOG_DOWNLOAD ON
    LOG_CONFIGURE ON
    LOG_BUILD ON
)

When we look at the contents on disk we see vtkm-prefix/src/vtkm-stamp/ being used for the log files not vtkm/stamp/:
