I am trying to install R packages, ComplexHeatmap, DESeq2 in the R installed in conda environment. I get same installation issue while installing any package.

 error: 'timespec_get' has not been declared in '::'
   80 |   using ::timespec_get;

-----------------------------[ ANTICONF ]-------------------------------
Configuration failed to find one of freetype2 libpng libtiff-4 libjpeg. Try installing:
 * deb: libfreetype6-dev libpng-dev libtiff5-dev libjpeg-dev (Debian, Ubuntu, etc)
 * rpm: freetype-devel libpng-devel libtiff-devel libjpeg-devel (Fedora, CentOS, RHEL)
 * csw: libfreetype_dev libpng16_dev libtiff_dev libjpeg_dev (Solaris)
If freetype2 libpng libtiff-4 libjpeg is already installed, check that 'pkg-config' is in your
PATH and PKG_CONFIG_PATH contains a freetype2 libpng libtiff-4 libjpeg.pc file. If pkg-config
is unavailable you can set INCLUDE_DIR and LIB_DIR manually via:
R CMD INSTALL --configure-vars='INCLUDE_DIR=... LIB_DIR=...'
-------------------------- [ERROR MESSAGE] ---------------------------

Configuration failed because libcurl was not found. Try installing:
 * deb: libcurl4-openssl-dev (Debian, Ubuntu, etc)
 * rpm: libcurl-devel (Fedora, CentOS, RHEL)
If libcurl is already installed, check that 'pkg-config' is in your
PATH and PKG_CONFIG_PATH contains a libcurl.pc file. If pkg-config
is unavailable you can set INCLUDE_DIR and LIB_DIR manually via:
R CMD INSTALL --configure-vars='INCLUDE_DIR=... LIB_DIR=...'

I did install the system libraries mentioned in the log, still the issue persists.What is causing this issue ? (I also removed the R installed on my system, to prevent any installation conflicts in conda environment)
